Indian-origin British MP Keith Vaz has called for the world-famous Kohinoor diamond to be returned to India during Prime Minister Narendra Modi's UK visit in November.

Vaz's comments came in response to Congress MP Shashi Tharoor's recent stirring speech at the Oxford Union calling for Britain to pay reparations to India for 200 years of its brutal colonial rule.

"I welcome Dr Tharoor's speech and the endorsement of its message by Prime Minister Modi. I share their views. These are genuine grievances which must be addressed. Pursuing monetary reparations is complex, time consuming and potentially fruitless, but there is no excuse for not returning precious items such as the Kohinoor diamond, a campaign I have backed for many years," said Vaz, the longest serving British MP of Asian descent.

Modi is due to arrive in the UK in November, and Prime Minister David Cameron has gone out of his way to maintain a strong bilateral relationship.

"What a wonderful moment it would be, if and when Prime Minister Modi finishes his visit, which is much overdue, he returns to India with the promise of the diamond's return," Vaz said.
